Numbness on one side of the head during sleep
Numbness on one side of the head during sleep may result from physiological factors as well as pathological causes such as autonomic nervous system dysfunction and cervical spondylosis. Symptoms can be improved through general management or medication. Specific analyses are as follows:
1. Physiological Factors
If a person lies on one side for an extended period, prolonged pressure on one side of the head may impair local blood circulation, leading to numbness upon waking. This is usually a normal phenomenon that does not require treatment. Symptoms typically resolve gradually after getting up and engaging in light physical activity.
2. Pathological Factors
a. Autonomic Nervous System Dysfunction
Long-term psychological stress or mental tension may lead to neurological dysfunction and autonomic nervous system imbalance, resulting in the aforementioned symptoms. Under medical guidance, patients may take medications such as oryzanol tablets or vitamin B1 tablets.
b. Cervical Spondylosis
Protruding cervical intervertebral discs may compress local blood vessels and nerve roots, causing vertebrobasilar insufficiency or occipital nerve compression, which can lead to scalp numbness on one side during sleep. Patients may follow medical advice to use medications such as mecobalamin tablets or vitamin B12 tablets.
In addition, conditions such as hypertension, cerebral arteriosclerosis, or cerebral infarction may also cause similar symptoms. It is important to seek timely evaluation and targeted treatment at a reputable hospital to prevent disease progression.
